Thanks for your Help. First try was a fail, because it says after some minutes "Out of Memory".. I try again tomorrow.. I think there was tooo much data. :)Maybe it will help, if I delete the Attachment-folder, or the files I don't need anymore (pictures and old PDFs)

In this case, when importing the messages, rather than selecting the option "All Folders", please select the option "Select Folders" and then try importing the individual folders into your current installation.

It take some time, but now the Messages are back in place. But I still missing some inbox-messages. But it isn't sooo important.

But I can't import the contacts. If I do like you wrote, it comes up an windows that try to import and then it says "There are no contacts in the IM-adressbook, that can be importet" (In german by the way). Do I something wrong, or ist maybe the file corrupt?I choose like befor the "identities" folder

In this case, please try importing the contacts from the "AddressBook" folders contained in each of the "Identities\{Some-Really-Long-Number}" folders, as the import does not always work from the parent "Identities" folder.

I hope that Incredimail will become a new version in future, that works better with windows 10.. For now it crashes much to often :(It is the best Email-Client I know, with wonderful Features. I hate, to use other clients..

I have to change my computer and want to retrieve all my e-mails, address book, letters, notifiers, ... on my new pc.

I copied my Incredimail identity on the new pc and imported the messages in Incredimail, but I do not have all the mails.When I look on the old pc, I see that the date of my Inbox.imm file is 12/12/2015. So I understand that's why I only have my mails until this date.However, on my old pc, I have mails from 12/12/2015 until 05/03/2017. I try to find another inbox.imm file, but do not find it.Did Something change in the structure of the files ?

I also see there is an option to transfer the data from an old computer to a new computer, but I miss one option, i.e. the option to export the data from the old computer. I only have the option to import the file data.cab from the old computer to the new.

Can you help me retrieving all my mails and by the way the letter I created on my old pc ?
